The Siemens SENTRON 3VA2110-6HN42-0AA0 is a 4-pole molded case circuit breaker rated for 100 A continuous current across its full ambient range — no derating needed from 40 °C up to 70 °C, which simplifies panel thermal budgeting in warm enclosures or near other heat sources. Its ETU350 electronic trip unit gives you adjustable long-time (tr 0.5–17 s) and short-time delay (tsd up to 0.4 s), plus selectable N-conductor protection (OFF, 50%, 100%), so you can shape the time-current curve for selective coordination downstream. The interrupting ratings are the headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.8 kA at 690 V — that is a high-fault-current MCCB sized for main or feeder duty in industrial switchboards where the available fault current is substantial.
The 3VA2110-6HN42-0AA0 measures 140 mm wide, 181 mm high, and 86 mm deep — a 4-pole MCCB footprint that fits standard switchboard mounting plates. Rated insulation voltage Ui is 800 V, and the operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C.
